Implementations

impl Error

pub fn is_retriable(&self) -> bool

Classify whether this error is retriable.

Permanent errors (not retriable) include authentication failures, configuration errors, and server-side rejections for invalid topics, producer fencing, authorization failures, etc.

Transient errors (retriable) include I/O errors, connection resets, timeouts, and generic server errors that may resolve after reconnect.

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<ProtocolError> for Error

fn from(source: ProtocolError) -> Self

Converts to this type from the input type.
